Well, you're in for an uphill battle. It's really hard to truly delete past history in git, but you can try if it hasn't spread far. 

If ABC is the name of your password file, you could do something like this:

git filter-branch --tree-filter "rm -rf ABC" --prune-empty HEAD

then push the change up. Try that.
